Нарушения иммунной системы в ранние сроки после COVID-19 ассоциированы с высоким риском развития других инфекций, в том числе вирусных. Диагностика последних затруднена, особенно при отсутствии клинических симптомов первичного инфицирования и вместе с тем тяжелом течении болезни. О развитии энцефалита в результате реактивации латентной вирусной инфекции ранее не сообщалось.</p><p>Описание клинического случая. У девочки в возрасте 4 лет отмечено появление психоневрологической симптоматики с присоединением на следующий день тонических судорог в конечностях. На 3-и сут после дебюта ребенок госпитализирован с предварительным диагнозом «вирусный энцефалит». В анамнезе — за 3–4 нед до дебюта заболевания — контакт с больными с лабораторно подтвержденной новой коронавирусной инфекцией с появлением у ребенка признаков легкой респираторной инфекции (на наличие SARS-CoV-2 обследован не был). После исключения широкого спектра инфекций (отрицательные результаты ПЦР на SARS-CoV-2, цитомегаловирус, вирус простого герпеса, вирус Эпштейна – Барр, токсоплазму, энтеровирус) заподозрена аутоиммунная природа поражения ЦНС (в последующем не подтверждена). На 15-е сут от дебюта заболевания в клетках крови и в мазке из ротоглотки обнаружен вирус герпеса человека 6-го типа. В эти же сроки обнаружена высокая концентрация IgG к SARS-CoV-2. Лечение (на разных стадиях болезни — антибактериальная, противосудорожная, антикоагулянтная, противовирусная, иммунозаместительная и седативная терапия, глюкокортикостероиды) не привело к положительной динамике болезни. По данным МРТ головного мозга (23-и сут от дебюта болезни) обнаружены зоны лейкоэнцефалопатии субкортикального белого вещества конвекситальных отделов теменных и затылочных долей, субатрофические изменения белого вещества полушарий мозга с умеренным викарным расширением субарахноидальных пространств. Прогрессирование заболевания привело к летальному исходу на 32-е сут после появления первых его признаков.</p></sec><sec><title>Заключение</title><p>Заключение. Показана возможность развития тяжелого вирусного энцефалита (в результате первичной герпесвирусной инфекции или ее реактивации) в ранние сроки после перенесенного легкого COVID-19. Причинно-следственный характер этой связи требует дополнительного изучения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Immune system disorders early after COVID-19 are associated with high risk of other infections development, including viral ones. Their diagnosis is complicated especially in the absence of clinical symptoms of primary infection and alongside with serious disease course. There are no reports on encephalitis development due to reactivation of latent viral infection.</p><p>Clinical case description. Girl, 4 years-old, had psycho-neurological symptoms followed by tonic seizures on the next day. The child was hospitalized on the 3rd day after disease onset with preliminary diagnosis of viral encephalitis. The child has contacted with patients with laboratory-confirmed new coronavirus infection 3-4 weeks before the disease onset, later she had signs of mild respiratory infection (no examination of SARS-CoV-2 was carried out). Autoimmune nature of central nervous system injury was suspected after excluding a wide range of infections (negative PCR results for SARS-CoV-2, cytomegalovirus, herpes simplex virus, Epstein-Barr virus, toxoplasma, enterovirus), however it was not confirmed later on. Human herpes virus type 6 was revealed via blood tests and oropharyngeal swаb on the 15th day of disease. High concentration of IgG antibodies to SARS-CoV-2 was found was revealed as well. Treatment (antibacterial, anticonvulsant, anticoagulant, antiviral, immunosupportive, and sedative therapy, glucocorticosteroids) did not achieve significant improvement. Brain MRI (on the 23rd day of the disease) has shown leukoencephalopathy zones in subcortical white matter of convexital surfaces of parietal and occipital lobes, subatrophic changes in white matter of cerebral hemispheres with moderate vicarious enlargement of the subarachnoid spaces. Disease progression led to patient’s death on the 32nd day after first signs appearance.</p></sec><sec><title>Conclusion</title><p>Conclusion. The development of severe viral encephalitis (as a result of primary herpes virus infection or its reactivation) in the early period after mild COVID-19 is shown. Its cause-effect relations require further examination.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>герпесвирусные инфекции</kwd><kwd>энцефалит</kwd><kwd>COVID-19</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>herpes virus infections</kwd><kwd>encephalitis</kwd><kwd>COVID-19</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Отсутствует</funding-statement><funding-statement xml:lang="en">Not specified</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Савенкова М.С., Вашура Л.В.
